get about 28K per second on crystal vs 20K on python.

unix-socket-client.cr

require "socket"

server_addr = "/tmp/uds_server.sock"

duration = 1

endtime = Time.now + duration.seconds
msgs = 0

puts "Receiving messages..."

while Time.now < endtime
  sock = UNIXSocket.new(server_addr)
  data = sock.receive(32)
  msgs += 1
  sock.close
end


puts "Received #{msgs} in #{duration} second(s)."

unix-socket-server.cr

require "socket"

server_addr = "/tmp/uds_server.sock"
if File.exists?(server_addr)
  File.delete(server_addr)
end

server = UNIXServer.new(server_addr)
puts "'Server ready."

while true
  server.accept? do |socket|
    socket.print "Hello there!"
  end
end
